Loudness Levels and Ensemble Room Acoustics

A previous paper (AES 92nd Convention) presented musicians' preferences for the acoustical design of music practice rooms. Acoustical design criteria and priorities have evolved from that information. The requirements for large-scale ensemble spaces will be discussed. The loudness levels of a typical brass and percussion ensemble were measured. These levels in turn can be used to refine the sound isolation requirements of ensemble practice rooms and the room volume/height requirements.
